I bought this not realising it was an XD adapter and not an XD drive – turns out the adapter didn’t fit my bike and I broke the lockring bit on it trying to get it out. 

The cassette itself is a 10-46t cassette and it’s completely unused. You can buy a new Sunrace XD adapter for £20 on Amazon, or if you’ve fitted one of these before you probably still have the adapter stuck on your XD drive. 

Anyway, I’m looking for around £50 but open to offers.
